This processor adds new key-value pairs to the log event.

For more information about this processor including examples, see addKeys in the CloudWatch Logs User Guide.

Example: 

 // Create a log group
 LogGroup logGroup = new LogGroup(this, "MyLogGroup");
 // Create a JSON parser processor
 ParserProcessor jsonParser = ParserProcessor.Builder.create()
         .type(ParserProcessorType.JSON)
         .build();
 // Create a processor to add keys
 JsonMutatorProcessor addKeysProcessor = JsonMutatorProcessor.Builder.create()
         .type(JsonMutatorType.ADD_KEYS)
         .addKeysOptions(AddKeysProperty.builder()
                 .entries(List.of(AddKeyEntryProperty.builder()
                         .key("metadata.transformed_in")
                         .value("CloudWatchLogs")
                         .build()))
                 .build())
         .build();
 // Create a transformer with these processors
 // Create a transformer with these processors
 Transformer.Builder.create(this, "Transformer")
         .transformerName("MyTransformer")
         .logGroup(logGroup)
         .transformerConfig(List.of(jsonParser, addKeysProcessor))
         .build();
